Long term changes in the chemical composition of the Earth's atmosphere induced by anthropogenic emissions and space based energetic particles can have a dynamical feedback on temperatures and winds of the Earth which can cause deviations in the weather ultimately leading to climate change. My research focuses on addressing these issues with the help of large climate models and observations. I analyze big datasets to better understand changes and underlying processes governing climate change. 

In my doctoral thesis I investigated the impact of atmospheric ionization on the chemical constituents using a state of the art 1D stacked box D-region ion-chemistry model. I worked on validating the 1D model ExoTIC, that has been extended to study exoplanets, with studies focused on chlorine and nitric oxide species and their contribution to ozone loss. 

Currently, I work with analysing big data from the EMAC model to study the dynamical coupling to the troposphere and changes induced by the gravity wave drag on wind circulation.
